BN_num_bits, BN_num_bytes, BN_num_bits_word ? get BIGNUM size |
#include <openssl/bn.h> int BN_num_bytes(const BIGNUM *a); int BN_num_bits(const BIGNUM *a); int BN_num_bits_word(BN_ULONG w); |
These functions return the size of a BIGNUM in bytes or bits, and the size of an unsigned integer in bits. BN_num_bytes() is a macro. |
The size. |
